Submit Feedback

The best way to send feedback is to file an issue at https://github.com/mario-bermonti/stimpool/issues.

Please let us know about your experience using stimpool. You can tell us about the things that you like, the things that can be improved, and the things that you would like stimpool to do.

If you are proposing a feature:

  • How it would help you and other users (mainly researchers).

  • Explain all the details of how it would work.

  • Keep the scope as narrow as possible to make it easier to implement.

  • Remember that this is a volunteer-driven project and for this reason it may not be feasible to implement the feature or it may take some time.

Write Documentation

stimpool could always use more documentation. You can contribute to the documentation by:

  • Fixing typographical, grammatical, or spelling errors.

  • Improving documentation that is unclear or incorrect.

  • Creating or improving examples and tutorials.

  • Writing blog posts, articles, and similar content that share how you are using this project and your best practices with us.

Report Bugs

You can report bugs at https://github.com/mario-bermonti/stimpool/issues.

Please provide all the details that are asked when you create the issue to make sure it is understood correctly.

Fix existing bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Set up the development environment

Ready to contribute? Here’s how to set up stimpool in your local development environment.

You will need Python 3.6+ installed.

  1. Fork the stimpool repo on GitHub.

  2. Clone your fork locally:

    git clone git@github.com:your_name_here/stimpool.git
    
  3. We use poetry to manage dependencies. Install it with the following command.

     curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python -
    
  4. Install the project, its dependencies, and the virtualenv:

     poetry install
    
  5. Make sure everything is working properly before making any changes by running poetry run invoke dev-tasks.

Development tasks (important side note)

In order to run anything inside the virtual environment every command has to be prefixed with poetry run <command>.

For example, to run python inside the virtual environment you would run poetry run python.

We have most of our development tasks pre-configured to run automatically with invoke. :grin:

The most important tasks are:

Command Description
dev-tasks Run all development tasks.
format Format code.
tests Run tests.
coverage Create coverage report.
lint Run all linting.
mypy Run mypy.
docs Build documentation.
clean Run all clean sub-tasks.

You can find see all the development tasks that pre-configured by running poetry run invoke --list.

Making changes

Workflow

We work by protecting master branch and only merging changes that don’t break existing functionality and are tested.

How do we do it?:

  1. We identify something that must change

  2. We create an issue on GitHub, if it doesn’t already exist

  3. We create a new branch named after the issue we want “fix” (issue-$TASKNUMBER)

  4. We make changes and test everything works

  5. Style the code

  6. We then create a pull request to master branch that is reviewed and if approved, it is merged into master

This way we achieve an easy and scalable development process that avoids merge conflicts and long-living branches.

In this method, the master branch always has the latest working version of the software, is stable, and is working.

How to make changes

Follow this steps when working on changes to the project. Please see the Workflow section for important details about making changes.

  1. Create a branch for local development. All the changes must be in this branch.

    $ git checkout -b name-of-your-bugfix-or-feature
    
  2. Run the all checks to make sure everything is working before making any changes

     $ poetry run invoke dev-tasks
    
  3. Add any changes you want

  4. Add tests for the new changes

  5. Run the tests and make sure they all pass

     $ poetry run invoke tests
    
  6. Edit the documentation if appropriate (this is required for new features)

  7. Make sure the changes to the documentation are correct and that the docs build

     $ poetry run invoke docs
    
  8. Make sure everything is fine (e.g., tests, code style, coverage)

     $ poetry run invoke dev-tasks
    

    If you find that something is not working as expected, fix it, check that it is working appropriately by running the appropriate invoke command (see Development tasks section).

     $ poetry run invoke <command>
    

    After it is fixed, run all development tasks again

     $ poetry run invoke dev-tasks
    
  9. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit
    

    Stimpool follows specific guidelines for commit messages:

    • Make a reference to the relevant GitHub issues in your commit message (e.g., Fix #1234) We use imperative mood for commit messages (fix x, instead of fixed x). See this commit guide. A tip is to use a title for your commit message that completes “This commit will…” [Fix issue X].

    • The subject line should have < 80 chars

    • Leave one line blank

    • [Optional] Explain any relevant details or decisions made

  10. Push your changes to GitHub

     $ git push origin name-of-your-bugfix-or-feature
    
  11. Submit a pull request through GitHub (see the Pull Request Guidelines section).

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests for new functionality.

  2. If the pull request adds functionality, the docs should be updated.

  3. The pull request should pass all tests and must work for all the supported Python versions. It must also pass all checks in the GitHub CI.

Feel free to submit your pull request early so we can discuss it and iterate on the process.

Tips

We really value your contributions and want to integrate your changes. The following are tips to improve the probability that your changes are accepted.

  • Make sure they don’t break existing functionality

  • Include tests for the changes you made

  • Commit often

  • Make small, easy to understand commits (i.e., atomic commits)

  • Keep your changes in the narrowest scope possible (e.g., create tutorial for using the X object)

  • It is recommended to open an issue before starting work on anything. This will allow a chance to talk it over with the maintainers and validate your approach.
